If I remember correctly this information is kept in the registry. Google should be able to find you the details.

As far as I know, you have to have a file path to get the icon - but it doesn't have to be a valid file of that type.
So use a temporary file and get the icon from that:

C#

string path = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString() + ".mp4");
FileStream file = File.Create(path);
file.Close();
Icon im = Icon.ExtractAssociatedIcon(path);
File.Delete(path);

That gets complicated: you need to start playing with this, which will require a DLLImport:
